by cr0ss'-bar"`30. vA"similar*crosszbar 'may` the levers carrying the :forward axle 5 have' their mountingupontle rear-end of the chassis and Vthat the levers carrying 'the rear axle A 6" have their 'mounting upon the for` ward endlof Athe chassis, inother-words'the rearen'd ofthe` chassis'is carried by the -fr` ward'faxle and theforwa'rdend of'thechas= sisis carried by the 'rearl aXle. The'p'ivotf ally mounted sleeve 26 together with the "slid-I ing bar' 27 i are provided `for 'precliiding l at eral 'relative sway of the axles and `fthe chas-j sis Aand any other suitable means oraccom-f plishing this purposel may. be usedl in* lieu of thestructi'ire` disclosed. From. the fore# going it will be apparent that vvarious modil ications of'my-invention injay ,be' employed without departing from the yspirit of my 'invention, wherefore Ido not limit'inyself'to the specific forms and structure disclosed herein.

Y VInthe operationof my device, obstruc- CII end of the chassis and the rear ends of the levers 8 and l0 can result because the pivotal mounting ot the rear ends of the levers S and l0 retain. a lixed relationship to the chassis. From the foregoing it Will be 'apparent that all of the shock must be met by the spring 20, and that a structure embodying my invention positively precludes any transmission otshock from the axles to the chassis and that all such shock must be and will be met by the yielding means, Which in this application is illustrated as a spring Q0, provided such yielding means is capable of and adjusted for performing this function properly.

`What I claim is:

l; In a device ot the class desiribed the combination of a iront and a rear axle,y a chassis comprising depending brackets at its front and rear ends, bell crank levers each comprisingia long and a short arm, each lever being pivotally mounted at the junction of its said arms to one of the brackets, the long arms of the levers extending longitudinally of the chassis and substantially from end to end thereof and having their free ends mounted upon the axles, and yielding means expansible and contractible in a plane substantially parallel With the hori- Zontal planes extending longitudinally oi the chassis and the levers and having a connection with the free ends of the shorter arms of the levers. Y

2. In a device of the class described the combination of a front and a rear axle, a pair oi bell crank levers for each axle, each lever comprising a long and a short arm, the front axle being attached to the free ends of the long arms of one pair of levers and the rear axle being attached to the freeiends of the long arms of the other pair of levers, a chassis, depending brackets carried by the chassis at theV front and rear ends thereof, the levers supporting` the front axle being pivotally supported by the brackets at the rear of the chassis and at the junction oi the long and short arms of the levers, the levers carrying the rear axle being` pivotally supported by the brackets at the front of the chassis and at the junction of the long and short arms of said levers, a bolt 1pivotally connected with the free end ot1 each ot' the shorter arms of the levers, and a coiled spring on each bolt andV bearing against its respective bolt and the bracket associated With the respective bolts for yieldingly resisting movement of the levers about their pivotal mountings on the brackets.

Y 3. In a device of the class described the combination of a chassis provided at its front and at its rear with depending brackets, a pair of bell crank levers each comprising a long and a short arm pivotally mounted upon each br cket, the longer arms of each bracket extending longitudinally of j the chassis and terminating` adjacent the end ot therchassis opposite to that end of the chassis on which such lever is pivotally supported, an axle at each end of the chassis and attached to the Vtree ends of the longer arms of the levers, a bolt pivotally attached to the free end of each shorter arm of the lever, a spiral spring for each bolt and through which the respective bolts extend, and abutment means carried by each bolt and engaged by one endy ot' its respective spring, the second end of the spring engaging its respective bracket.

4. In a device of the class described the combination of 'a chassis provided at its front and Vat its rear with depending` brackets, a pair of bell crank levers each comprising a long and a short arm pivotally mounted upon each bracket, the long and` short arms extending from one another at substantially a right angle, the longer arms of each bracket extending longitudinally ot' the chassis and terminating adjacent the end of the chassis opposite tothat end ofthe chassis on Which such lever is pivotally supported, an axle at each end of the chassis and attached ,to the free ends of the longer arms of the levers, a bolt pivotally attached to the free end of Veach shorter arm of the lever, a spiral spring for each bolt and through Which the respective bolts extend, and abutment means carried by each bolt and engaged by one end of the spring, the second end of its respective spring engaging its respective bracket, the bolts extending in substantial Vparallelism with the chassis whereby movement of the levers about their pivotal mountings serves to reciprocate the bolts longitudinally of themselves and in parallelism with the chassis against the yielding influence of the springs.

5. In a device of the class described the combination of a chassis provided at its front and at its rear With dependin@ brackets, a pair of bell crank levers eacli comprising along and a short arm pivotally mounted upon each bracket, the longer arms of each bracket extending longitudinally of the chassis and terminating adjacent the end of the chassis opposite to that end of the chassis on which such lever is pivotally supported, an axle at eachend of the chassis and attached to the free ends of the longer arms of the levers, a bolt extending from the shorter arm of each lever and a spiral spring carried by each bolt and operative upon the chassisk and its respective lever for yieldingly resistingmovement of the lever.

6. In a device of the class described the combination of a chassis provided at its front and at its rear with depending brackets, a pair of bell crank levers each comprising a long and a short arm pivotally mounted upon each bracket, the longer arms o each bracket extending klongitudinally of the chassis andl terminating adjacent the end of thechassis opposite to that end of the chassis on which such lever is pivotally supported, an axle at each end of the chassis and attached to the free ends of the longer `arms of the levers, a bolt extending from the short# er arm of each lever, a spiral spring carried by each bolt and operative upon the chassis and its respective lever for yieldingly resisting movement of the lever, and means extending between the free ends of the levers and the chassis for precluding relative lateral motion of the chassis and axles.

7. In a Vdevice of the class described the combination of a front and a rear axle, a chassis comprising depending brackets at its front and rear ends, bell crank levers each comprising a long and a short arm, the arms extending from one another at substantially a right angle, each lever being pivotally' mounted at the junction of its said arms to one of the brackets, the long Varms of the chassis.

8. In a device of the class described the combination of a chassis provided with depending brackets intermediate its ends, a front and a rear axle at the opposite ends of the chassis, a bell crank having a. long and a short arm pivoted at the junction of the arms to each depending bracket, the arms extending from one another` at substantially a right angle, the long arm of each* vbell crank extending'in the direction of the length of the chassis and having its free end secured to an axle, and yielding means exl tending longitudinally of the chassis and the levers and having a connection with the Vfree ends of the shorter arms of the'levers,

one end of the .yielding means being free whereby lthe shocks directed against the axles are not transmitted to the chassis.

InA testimony whereof, I have hereunto subscribed my name this 11th day oi June 1923.
